Even if that’s true, it’s against professional conduct to provide therapy to family members (in this case a minor in her own direct care).I don't know if it has been mentioned, but her Aunt is the Professional Psychiatrist. It is the reason she can do the hypnotizing on him.
At a minimum there should have been another psychiatric professional who was part of the care team and monitoring his case, but normally he should never have gotten treatment from his own Aunt.
It’s impossible for her to act objectively. In fact it’s even worse because she should have known best that he needed proper therapy and instead just fucked with his programming and waited for it to fix itself.
She should lose her license for this malpractice.
